Powering the PI 4 and Breadboard

Blinking Red LED on Raspberry PI 4 and Breadboard powering

I had a Blinking Red LED on Raspberry PI so have now used an external power supply from an old DVD player. Have used the 12V via a voltage regulator to power up the PI 4 and also the breadboard for projects.

!! re-use items from old units if you can.!!
